CAR STOP Filed July 22, 1942 IN VENTOR. 3

Patented Mar. 9, 1943 UNITED STATES ATENT OFFICE This invention relates generally to car stops and more particularly to a rail chock having base flanges which secure it to the rail for stopping and holding mine cars on a grade.

The principal object of this invention is the provision of a simple and economic car stop that may be readily applied to and removed from a rail for checking and holding mine cars on a grade and will not break or get out of order because of rough usage or corrosion.

Another object is the provision of a simplified means for locking the chock on a rail to prevent accidental displacement.

Other objects and advantages appear in the following description and claims.

In the accompanying drawing a practical embodiment illustrating the principles of this invention is shown wherein:

Fig. l is a view in side elevation of the mine car stop comprising this invention.

Fig. 2 is a View of the eye bolt locking member.

, Fig. 3 is a view showing a mine car wheel on a rail in side elevation with the car stop applied thereto.

Fig. 4 is an end view of Fig. 3.

Referring to the drawing, the car stop l9 and the locking member l I are preferably made from one and one quarter inch steel bar stock. This stock may have any cross sectional shape but the round bar stock is more easily handled and there are no corners to wear away and change the normal or customary slant of the iron when in operation.

The car stop is bent into the shape of a printed S as illustrated in Fig. 1. The lower bight l2 and the top flange [3 of the S-iron serve as handles for grasping the car stop and shoving it into position on the rail 14 with the lower flange I5 underneath the foot of the rail and the intermediate section [6 resting on the head of the rail. It will be noted that the top flange I3 is somewhat longer than the intermediate section I 6 to provide a better grip.

The space between the lower flange l5 and the intermediate section [6 should be greater than the over-all height of the rail 14. Thus when the car stop is inserted on the rail it will lean to one side or the other until the lower flange l5 and the intermediate section [6 engage the foot and the head of the rail respectively, as shown in Figs. 3 and 4. It is preferable to have the lower flange [5 against the tie I? as shown in Fig. 3 and to permit the car stop to lean or slant downhill or away from the mine car so the force of impact is received and resisted by the car stop without having to move the latter to this position.

If the mine car strikes the car stop with considerable force it will rebound and the reactive forces may swing the car step toward the car. This action may be continued until the car finally comes to rest. Movement of the car stop in this manner may accidentally dislodge it from the rail, but to prevent this from happening a locking member I I is mounted on the .S-iron. The looking member l l is provided with an eye 18, the bore of which loosely fits the flange I3. A lug I9 is welded on the bend to hold the eye of the locking member I I on the horizontal part of the top flange lit. The locking member is maintained in position by means of the washer 20 which is welded to the top flange after the locking member is placed thereon. The spacing of the washer'20 with the lug I9 is suflicient to permit the locking member to rotate freely.

The length of the intermediate section [6 is sufficient to accommodate the rail 14 between the lower'end of the locking member II and the bight 12 as shown in Fig. 4. The length of the locking member is sufiicient to permit it to swing freely above the foot of the rail. However it engages the side of the rail head and prevents the car stop from being accidentally displaced in the presence of vibration or impact'forces of the car wheel. The eye bolt locking member may be swung to either side of the s-iron but in practice it is better to retain it on the side away from the mine car so that it may hang free in the vertical position, as shown in Fig. 3. The lower end of the locking member ll extends materially below the head of the rail and its weight will prevent it from swinging sufliciently high due to vibration or permit it to release. By grasping the bight l2 and the locking member II the car stop may be readily withdrawn after the locking member is swung upwardly to clear the rail.

I claim:

1. A car stop comprising a bar shaped to provide an open sided pocket which, when the stop is slid onto the rail from one side of the latter, embraces the rail, the upper portion of the bar being then positioned in the path of a car wheel, and a member carried by the upper portion of the bar and arranged to depend along the other side of the rail to prevent the accidental dislodgment of the stop from the rail.

2. A car stop comprising a bar shaped to provide an open sided pocket which, when the stop is slid onto the rail from one side of the latter, embraces the rail, the upper portion of the bar being then positioned in the path of a car wheel, and a member carried by the upper portion of the bar and arranged to depend along the other side of the rail to prevent the accidental dislodgement of the stop from the rail, the pocket having sufiicient play in respect to the rail to permit the stop to assume a tilted position on the rail.

3. A car stop comprising a bar shaped to provide an open sided pocket which, when the stop is slidonto the rail from one side of the latter, embraces the rail, the upper portion of the stop being then positioned in the path of a car wheel, and a member pivotally suspended from an upper portion of the stop in such loca in such location as to depend along the other side of the rail to prevent the accidental dislodgment of the stop from the rail, said member being swung aside to permit the stop to be removed from the rail.

7. A car stop comprising a bar of substantially S-shape forming upper and lower bights, the lower bight providing an open sided pocket which, when the stop is slid onto the rail from one side of the latter, embraces the rail, the upper bight of the stop being then positioned in the path of a car Wheel, and a member pivotally suspended from an upper portion of the stop in such position as to depend along the other tion as to depend along the other side of the 13 El i f the rail to prevent the accidental disrail and prevent the accidental dislodgment -o fthe stop from the rail, said memberbeing swun lodgment of the stop from the rail, the pocket formed by the lower bight having sufficient play aside to permit the removal ofthe stop frdm" the rail.
